These fuel rails are CNC machined from 6061 aluminum, black anodized, and laser etched. Each rail carries six 8AN ORB ports tapped 3/4-16, twelve ports in all, which leaves room to place the feed, crossover, regulator, gauge, and pulse damper connections wherever the build needs them. Radium classes this as an upgrade rail, so the OEM injectors carry over and any replacement must match the OEM height and O-ring sizes. Stainless steel mounting feet and stainless steel mounting hardware are supplied; 8AN ORB fittings are chosen separately to suit the plumbing.
